When i do ng build --target=production --environment=prod

it keeps generating a reference to js.map file for hammer

Then when i do a refresh or redirect in the url i get this message:
Failed to parse SourceMap: https://ethnicfoods-b928a.firebaseapp.com/hammer.min.js.map

Fixed in #2519 I believe. If you still have the same problem with the next release, let me know and I'll reopen.

I updated to cli 1.0.0-beta.17
But i stil see the sourcemapping .
So to be sure, am I right that there should not be a reference to a map
file of hammer when i made this build ?
ng build --target=production --environment=prod

What does this mean? declaration in unreachable code should be dropped?

Since #2519 didn't fix it for you I'll reopen.

Can you give me exact repro steps to get this behaviour? If I start with a brand new CLI app, what do I need to do to see it?

Your last three comments should have images I think, but none appeared here.

[stefanaerts]

1)I install hammerjs, so i have a folder node_modules/hammerjs
2) i add to angular-cli.json the following configuration:
"scripts": [
"../node_modules/hammerjs/hammer.min.js"
],

3. ng build --target=production --environment=prod

4. So now there is a dist folder:
   This is the content of the folder:
   [image: Inline image 1]

Do you see the picture above this line?

So as you can see there is a
-inline.js

• main..bundle.js
• main..bundle.js.gz
• scripts..bundle.js
• scripts..bundle.js.gz
  -styles..bundle.js
  -styles..bundle.js.gz

5. So as there are no js.map files in dist folder i would expect that for
   hammerjs there is no reference anymore to a js.map file in the generated
   scripts.<uniquenumber.bundle.js file.

But as you can see in thsi picture below this line there is line in the
file that contains:
(window,document,"Hammer");\n//# sourceMappingURL=hammer.min.js.map

[image: Inline image 2]

6. So when I deploy this to firebase and i open the application(firebase
   url) in my browser i get in the console the message
   Failed to parse SourceMap : https://.
   firebaseapp.com/hammer.min.js.map

So i guess the angular-cli/webpack chaking/minify/whatever stuff is not
working correctly for the 3th party hammerjs minified js file ?

Maybe its because its already minified?

Kind Regards,
Stefan.

@stefanaerts I solved it by referencing the non-minified version of hammer.

[stefanaerts]

@devCrossNet
As i expected, thanks for verifying.
@filipesilva So this means we should not include minified files in the angular-cli.json configuration file?
I also added this line to styles.css
"@import '~@angular/material/core/theming/prebuilt/deeppurple-amber.css';"

Thats also gave a reference to a .map file in the dist/styles..bundle.js

[filipesilva]

@stefanaerts you should be able to use both minified and un-minified versions in the scripts/styles array. I think this is a bug in how we process those files. Will look into it.
